Embodiments of the present invention relate to a technology about tempered glass doors installed in the entrances of houses or buildings, and more particularly, to a door locking system for fixing a glass to a frame tightly and strongly by providing a stopper to the frame and putting a captive bolt to the frame, and setting a tempered glass into a hole of the frame and tightening the captive bolt for the stopper to be pressed against the tempered glass such that the tempered glass can contact the frame closely and can be fixed to the frame tightly and safely, thereby to improve the durability of the tempered glass and the frame further and make their assembling and disassembling easier and enhance the construction and work ability.
Generally, doors are installed in buildings for entry of people, and there are many types for such doors, for example, classified as sliding doors, hinged doors, rotary doors, and so on. Particularly, there are installed inward/outward opening and closing, that is, hinged-typed doors in public buildings, department stores, hotels, big buildings, etc. in which lots of people are coming and using and therefore, tempered glasses are mostly set for such doors.
Regarding the tempered glass door, its exterior appearance is pretty, and even with the door closed, views outside the door can be well seen through glasses and persons entering buildings can be also well checked. Further, a safety cover is installed in order to prevent accidents during entry process, such as hands or clothes of passing persons caught therein, or carrying bags or conveyed objects being also caught there into.
Conventional tempered glass door was generally made with a tempered glass and a frame in which the tempered glass was put and fixed into upper and lower frames horizontally aligned and displaced, and then, the frames with the tempered glass are installed in the frames of the door entrance ends or rotatably to the door frames for opening/closing type.
As representative conventional technology for fixing the glass door, there has been disposed Korean Patent Registration No. 10-0452229 (Fixing Apparatus for Glass Door).
In the conventional technology as above, a glass is installed fixedly to a glass door directly without use of frames so as to provide visual satisfaction for beauty and even for long time usage, opening/closing state desired by a user can be stably maintained, and its maintenance and correction was easy and simple.
Further, as representative conventional art technology of safety door for increasing indoor energy efficiency, there has been disposed Korean Patent Registration No. 10-1144650 (Tempered Glass Safety Door with Improved Insulating Ability).
The conventional technology as above is characterized in that the horizontal door frame and the vertical door frame to form the frames of the tempered glass safety door show the heat insulation capability in itself, and thus, provides the effect of increasing indoor heat save performance and also energy save efficiency.
However, the conventional technology has defects of poor durability because its tempered glass is not fixed firmly to its upper and lower frames, and furthermore, its installation work in the location is very difficult to meet the inclined slope of the door frame in relation to the bottom surface of the entrance in the installation location, and the construction work ability is decreased because its assembling and disassembling was complicated.
In an embodiment, a door locking system is provided including: a frame (10) including a hole (11) and a stopper hole (12), wherein the hole (11) is formed inside the frame (10), wherein a door glass (60) is fitted in the hole (11, wherein the stopper hole (12) is recessed from the hole (11) into a first sidewall of the frame (10); a captive bolt (20) inserted into the first sidewall of the frame (10) in a first direction toward the stopper hole (12); and a stopper (30) fitted in the stopper hole (12), wherein the second direction is perpendicular to the first direction.
The door locking system may further include: a coupling hole (13) formed through the first sidewall of the frame (10) in the first direction, wherein a screw thread is formed on an inner wall of the coupling hole (13); and a long hole (14) formed inside the first sidewall of the frame (10) and extending along a longitudinal direction, wherein the longitudinal direction is perpendicular to the first direction.
The door locking system may further include: a coupling part (17) extending from the first sidewall of the frame (10) to between the long hole (14) and the stopper hole (12); and a cut part (16) formed through an upper portion of the frame (10) and communicating with the long hole (14), wherein the coupling part (17) extends up to the cut part (16).
The stopper (30) is in a thin-rod shape. A pressure groove (31) is formed on the stopper (30) to receive the captive bolt (20).
Embodiments of the present invention provide a door locking system for tempered glasses in order to solve the problems in the conventional door fixing system for tempered glass in that the durability becomes decreased because the tempered glass cannot be fixed firmly to its frame, and the construction work ability becomes decreased because the assembling and disassembling in the door glass fixing are complicated, and thus, provides a door glass fixing system which is mainly composed of a frame, a captive bolt, and a stopper, and is processed by setting a stopper in the frame of the door while putting a captive bolt into the frame, and inserting one sheet of tempered glass into the hole of the frame, and then, tightening the captive bolt for the stopper to keep pressing the tempered glass which comes to contact closely and tightly with and be firmly fixed to the frame.
Further, the present invention is directed to provide a glass fixing system to door for increasing the durability by fixing tempered glass to the frame through a stopper tightly and strongly and increasing the construction work ability by making its assembling and disassembling simple and easy and also, for making the glass fixing process more simplified at the entrance of installation location by checking the bottom surface of the entrance and the slope of the door frame.
In accordance with an aspect of the present invention, the door locking system may include frames displaced to be aligned with each other at the upper and lower portions of a door glass, the frame having a hole into which the door glass is inserted and fixed, and a stopper hole formed at one side of the hole; a captive bolt to be engaged with one side of the frame; and a stopper inserted and provided inside the stopper hole of the frame.
Further, in the embodiment of the present invention, the frame may include a coupling hole with screw threads like nut grooves through its side portion where the stopper hole is formed; and long holes formed along the longitudinal direction, at its upper both portions, and at its middle and lower portions.
Further, in the embodiment of the present invention, the stopper is formed as bar-shaped thin rod in thickness, and a pressure groove can be formed on the middle at side.
Therefore, the present invention provides effects of fixing tempered glass to a frame strongly to improve their durability and making simplified their assembling and disassembling process to increase the construction work ability, since the stopper is provided in the frame, and the captive bolt is inserted into the frame, and tempered glass is placed to be put into the hole of the frame while the captive bolt comes into and tightens further so that the stopper applies pressure on the tempered glass and can be closely and tightly contacted there with.
Further, the present invention provides effects of fixing tempered glass to the frame through the stopper firmly, increasing the construction work ability by their simplified assembling and disassembling process, and making easier the installation work at the door entrance corresponding to the bottom surface of the entrance and the slope of the door frame.
